Looking at the code for this plugin, is laugh out loud bad. It is, without doubt the worst plugin code I have ever seen. It is like this company was trying to write a plugin that ignored every wordpress standard ever.

I am suspicious about this company.
Could it be a giant ponzi type of operation?

The plugin virtually has no useful options. Can't verfiy the key and many people have same issue.
Yet, they claim to be a well funded company with worldwide offices and the sheer number of jobs apparently being offered is way more than even Sony or Apple.
